Injuries have given Laurence Maguire his first chance to wear the Spireites' first-team shirt - and now the teenager is looking to keep hold of it.
After graduating from the academy over a year ago it was a long wait for Maguire's call to make a Spireites start, but come Gillingham and his assured debut suggested many more appearances could follow.
"It came as a surprise when I got the call about starting," said Maguire. "I came into training and got on with things, then we did a bit of shape and I was in there. Dion (Donohue) had done his knee and then Paul McGinn had done his hamstring so I knew I had a chance of a starting place, and while I'm not generally a left-back I will work hard there if I need to.
"The first game you know you're going to be nervous but I thought I did well, it was disappointing to concede in the last minute but we moved on to Bradford. I did okay again, but it was tough to lose and only get one point from the six available.
"It is harder at this level, it's completely different to the reserves where things are slower. This tempo is higher and with playing at left-back it's hard on the legs as I'm not used to getting up and down the wings. I've been trying to get forwards and that's what the gaffer wants, so I'm working on that."
For the 19-year-old his three successive starts came after a tough first year as professional in 2015/16: "It feels great, I've been aiming for this for a long time now," he said. "I had a year last year that was a bit disappointing for me. I wasn't in and around the squad and just played reserve team football.
"I thought that this year I started well in pre-season and now the gaffer's given me the opportunity in the last couple of weeks, it's good to know that he has the faith in me."
Now a confirmed member of the first-team squad, Maguire has been taking advice from his older colleagues as he aims to make sure the starting berth remains his.
"My team-mates have been great," he said. "Everyone participates in the dressing room. Lids (Gary Liddle) the skipper, Sam Hird, Evo (Ian Evatt) are all experienced pros and they help out and praise you when you need it.
"Morgs (Chris Morgan) is good with me as well, he used to be a centre-half so it's good to have someone like that around who played in my position.
"We have a few days for rest and recovery this weekend without a game, I need to come in on Monday, train as well as I can and hopefully show the gaffer that I should keep the shirt next Saturday."
